Definitions

  • the invention relates to a method for actuating ink discharge elements in an array of elements of a print head in accordance with a predetermined pattern of drops.
  • the invention further relates to a print system.
  • High volume, high speed cut-sheet and webprinters are known.
  • Contemporary colour print systems of these kinds apply coloured ink, comprising any material or mixture in a liquid state, to a substrate using a print head for discharging ink drops in accordance with image data.
  • the print head comprises an array of discharge elements, the array stretching along a width of the substrate. While the print head is fixed, the substrate is transported along an ink discharging side of the print head in a direction perpendicular to the direction of the array.
  • the print head is capable of jetting ink drops at such timings that lines of dots result on the substrate, enabling the reproduction of an image on the substrate.
  • the ink is supplied to the elements through an ink channel in the print head. Due to the high print speed of the print systems, an ink flow through these channels can be as high as 10 to 100 ml/min.
  • Each of the ink discharge elements, or print elements is provided with a nozzle to discharge ink from.
  • Each of the elements further comprises an actuator that converts an electric signal into a mechanical displacement, thus either expanding or contracting an ink pressure chamber. If the electric signal is sufficiently large, an ink drop is created at an end of the nozzle of the print element.
  • This ink drop discharging signal may comprise several pulse shapes at predetermined timings in order to generate a required droplet and to leave as little as possible pressure fluctuations in the ink pressure chamber, such that the ink discharge element is left ready to produce a further ink droplet.
  • An image comprising a set of dots on predetermined positions may be reproduced on the substrate by appropriate timing of ink drop discharging signals to the array of print elements. At positions where no dot is required, no actuation of the corresponding print elements is applied, which is described in this disclosure as providing a null signal.
  • a known method for actuating a print element comprises, in addition to applying a discharging signal to obtain an ink drop and to applying a null signal to refrain from an ink drop, a non-discharging signal that causes a pressure wave in the ink pressure chamber of an element without generating a drop from the corresponding nozzle.
  • This signal may comprise the same or another set of pulse shapes as a discharging signal, as long as the amplitude or the duration of the signal is sufficiently small.
  • This non-discharging signal may be applied regularly to bring the ink in the pressure chamber and the nozzle into motion, thereby preventing clogging of ink in the nozzle.
  • Ink clogging may result in a clogged nozzle, leading to a malfunctioning print element, thereby possibly deteriorating the printed image quality.
  • a nozzle has not been applying an ink drop for some time, it has proven to be practical to use a non-discharging signal for actuating a print element.
  • This non-discharging signal is mainly applied just before a discharging signal is scheduled in order to bring the ink in a nozzle into motion, thereby improving the effectivity of a discharging signal that is not preceded by another discharging signal.
  • a non-discharging signal may be used instead of no activation signal at all, both not resulting in an ink drop.
  • a disadvantage of using non-discharging signals is that it leads to additional energy dissipation in the print head, thus possibly raising its temperature, or alternatively, necessitating supplemental cooling of the print head. It goes without saying that a non-discharging signal can only be applied if no dot is required at a corresponding position on the substrate.
  • a further use of a non-discharging signal is disclosed in the US patents US 5,831,650 and US 6,331,052 wherein this kind of signal is used to counteract a mechanical crosstalk effect of a neighbouring print element that is actuated by a discharging signal.
  • the use of a non-discharging signal may in this case facilitate the contraints to the stucture of a print head.
  • a problem with the above-mentioned method of working is that the productivity, that is the number of prints that is printed per unit of time, decreases, since the procedure is applied precautionarily to avoid obtaining defective prints.
  • a further probem is that a large amount of ink is wasted. It is therefore an object of the present invention to apply an activation scheme to the print elements that maintains a high productivity without loss of ink.
  • a method for actuating ink discharge elements in an array of elements of a print head comprises the steps of:
  • a non-discharging signal to a print element is thought to prevent air leaking into the print element.
  • a ratio of non-discharging versus null signals is 40%.
  • the ratio in step b) approaches 100% if the amount of discharging signals approaches a maximum. Since there are always some print elements that are not involved in generating ink drops, e.g. at the edges of a print head, there are always elements that are susceptible to the effect of air leaking in, which is stronger the more print elements are jetting ink drops. Thus, at maximum of print elements discharging a drop of ink, it is advantageous to provide all non-discharging elements with a non-discharging signal instead of a null signal.
  • At least one non-discharging signal is applied if the amount of discharging signals is above 50% of all the signals provided to the print head.
  • the invention may advantageously be embodied in a print system for imagewise printing dots on a substrate, the system comprising a control unit configured for executing one of the methods described above.
  • Figure 1 shows a sheet of a receiving medium, P, being transported in a direction for conveyance as indicated by the arrows 50 and 51 with the aid of transportation mechanism 12.
  • Transportation mechanism 12 may be a driven belt system comprising one (as shown in Fig. 1 ) or more belts. Alternatively, one or more of these belts may be exchanged for one or more drums.
  • a transportation mechanism may be suitably configured depending on the requirements (e.g. sheet registration accuracy) of the sheet transportation in each step of the printing process and may hence comprise one or more driven belts and/or one or more drums.
  • the way of fixation is not particularly limited and may be selected from electrostatic fixation, mechanical fixation (e.g. clamping) and vacuum fixation. Of these vacuum fixation is preferred.
  • the printing process as described below comprises of the following steps: media pre-treatment (14), image formation (11), drying and fixing (20) and optionally post treatment (not indicated).
  • a media pre-treatment 14 is applied to improve the spreading and pinning (i.e. fixation of pigments and water-dispersed polymer particles) of the ink on the receiving medium P, in particular on slow absorbing media, such as machine coated media, prior to printing an image on the medium.
  • a pre-treatment module comprising a pre-heating unit 13, for example a radiation heater, a roller coating unit with two rollers 16, 17 providing an aqueous pre-treatment liquid to the coated printing paper P from storage tank 15, and a drying member 18 that reduces the quantity of the water content in the applied coating.
  • Each surface of the double rolls 16, 17 may be covered with a porous resin material such as sponge.
  • Alternative methods of application of a pre-treatment liquid include an ink-jet application, a curtain coating and a spray coating.
  • a roller coating method as in Fig. 1 , is preferable because this coating method applies the pre-treatment liquid homogeneously to a recording medium.
  • the amount of the applied pre-treatment liquid with a roller or with other means to a recording medium can be suitably adjusted by controlling the physical properties of the pre-treatment liquid, the contact pressure of a roller in a roller coater to the recording medium and the rotational speed of a roller in a roller coater which is used for a coater of the pre-treatment liquid.
  • an additional pre-treatment method may be provided by a corona or plasma treatment unit, wherein a sheet of a receiving medium is exposed to a corona discharge.
  • the adhesion and spreading of the pre-treatment liquid and the ink is improved by increasing the surface energy of the media.
  • the step of image formation 11 is applied by four ink jet marking devices 111, 112, 113, and 114, positioned above the belt transporting the receiving medium P. Each device is as wide as the width 52 of the medium, thus making lateral movements of the devices unnecessary.
  • the devices are provided with ink in the colours cyan, magenta, yellow and black to produce a full colour print using a CMYK subtractive colour mixing scheme.
  • the digital signals, or print signals, to control the individual liquid discharge elements of the marking devices are composed by the control module 30 from image data 25 using a high speed connection 32.
  • An ink jet marking device as indicated above is also known as a page wide array and comprises a number of print heads wherein the discharge elements are also referred to as print elements, or nozzles, a nozzle being the part of a print element where the ink drops originate.
  • Ink is supplied to the individual print elements through a channel in a print head. Not shown is a maintenance position wherein the marking devices are brought for flushing, purging and wiping the devices.
  • Each of the inkjet marking devices 111, 112, 113, 114 has a length of at least the width 52 of the desired printing range.
  • the inkjet marking device may comprise a single print head or may be constructed by combining two or more print heads, such that the combined lengths of the individual heads cover the entire width of the printing range.
  • Such a constructed inkjet marking device is also termed a page wide array (PWA) of print heads.
  • the print heads may have a staggered arrangement to provide a PWA with nozzles which are substantially equidistant in the length direction of the inkjet marking device.
  • the staggered configuration may provide a redundancy of nozzles in an area where the inkjet heads of a first row and a second row overlap.
  • Staggering may also be used to decrease a nozzle pitch, thereby increasing the print resolution, in the length direction of the inkjet marking device.
  • the resolution may be further increased by using more rows of print heads, each of which are arranged such that the positions of the nozzles of each row are shifted in the length direction with respect to the positions of the nozzles of other rows.
  • the image formation may be carried out while the receiving medium P is temperature controlled.
  • a temperature control device 19 may be arranged to control the temperature of the surface of the transportation mechanism underneath the inkjet marking module 11.
  • the temperature control device 19 may be used to control the surface temperature of the receiving medium P, for example in a range of 30°C to 60°C.
  • the temperature control device 19 may comprise heaters, such as radiation heaters, and a cooling means, for example a cold blast, in order to control the surface temperature of the receiving medium within said range.
  • the receiving medium P is conveyed to the down stream part of the inkjet marking module 11.
  • the prints are dried and the image is fixed onto the receiving medium. Drying comprises the evaporation of solvents, in particular those solvents that have poor absorption characteristics with respect to the selected receiving medium.
  • Fig. 1 schematically shows a drying and fixing unit 20, which may comprise a heater, for example a radiation heater.
  • a drying and fixing unit 20 After an image has been formed, the print is conveyed to and passed through the drying and fixing unit 20. The print is heated such that solvents, in the present embodiment to a large extent water, in the printed image evaporate. The speed of evaporation and hence drying may be enhanced by increasing the air refresh rate in the drying and fixing unit 20. Simultaneously, film formation of the ink occurs, because the prints are heated to a temperature above the minimum film formation temperature.
  • the residence time of the print in the drying and fixing unit 20 and the temperature at which the drying and fixing unit 20 operates are optimized, such that when the print leaves the drying and fixing unit 20 a dry and robust print has been obtained.
  • the transportation mechanism 12 in the fixing and drying unit 20 may be separated from the transportation mechanism of the pre-treatment and printing section of the printing apparatus and may comprise a belt or a drum.
  • Figure 2 shows a test image 60 for a high coverage, long run test.
  • the black parts, such as 61, of the test image indicate where any of the available inks is to be applied.
  • the coverage of the image is about 80%.
  • Some print elements at the side of the image are not applied at all. These are the ones most susceptible to be the origin of an epidemic failure in a long run, e.g. more than 100 prints in a row, directly after one another.
  • Fig. 3 shows an embodiment of the individual steps of the invention. These steps are carried out in control module 30 when converting image data to print signals.
  • S1 the number of elements of a PWA is determined. Note that it is not necessary to know the exact configuration of the PWA, only a number N of elements that are to be controlled is to be determined. This may include elements that are used several times for a specified image area. Furthermore the number D of dots that are required in this area is to be determined. The number of dots corresponds to the number of print elements that is activated with a discharging signal, i.e. a print signal that makes the print element discharge a drop of ink.
  • S2 a coverage is determined by dividing D by N.
  • step S3 a loop is started for each print element in the set. First, it is checked in step S4 if the element is associated with a dot. If yes (Y), a discharging signal is attributed to the print element in step S6 and the loop proceeds to the next element. If no (N), in step S5 a random number between 0 and 1 is selected and compared to the ratio of step S2: if the random number is smaller than the ratio, branch Y, a non-discharging signal is attributed to the print element in step S7.
  • step S8 a null signal is attributed in step S8.
  • all print elements receive one of the three indicated print signals. Note that when the ratio is large, it will often happen that a random number is smaller than the ratio, thereby increasing the number of non-discharging signals relative to the number of null signals. According to the invention, this is correlated to a situation of high coverage.
  • the relation 70 between the coverage and the ratio relates a high coverage, indicated on the horizontal axis 71, to a high ratio, indicated on the vertical axis 72.
  • a ratio of 0 is selected for low values of the coverage.
  • a high ratio is selected for high values of the coverage, up to a maximum, usually 1, or 100%.
  • a number of non-discharging signals remains restricted, keeping an associated heating effect limited, and at the same time, a number of non-discharging signals is applied to diminish a risk of air leaking into non-used print elements.
